“Tryweryn was a remarkable period in history, which had a profound impact on us,” said Dr Huw Griffiths, senior lecturer at University of Wales Trinity Saint David.

He said the vast majority of teaching around Tryweryn was taught by Welsh language departments in secondary schools, and there needed to be a refocus on local Welsh history in schools.

“Our children still leave school knowing more about Nazi Germany than Welsh history,” he added.

The Welsh government said Welsh history had been “mandatory as part of the Curriculum for Wales since 2022”, including learning about children’s own locality.

“Learners are taught how history, language, diversity and culture have shaped Wales to become the proud and unique nation it is today,” it added.

But Mr Griffiths argued that secondary education in Wales was often guided by GCSEs and A-Levels, which he said meant the tales of “who we are as people get lost”.

“It’s about a deeper understanding of who we are, developing an idea of belonging and who we are as people,” Dr Griffiths added.
